By default, it caches a single instance of the ZoneInfoFile object and returns that. :param new_instance: If ``True``, a new instance of :class:`ZoneInfoFile` is instantiated and used as the cached instance for the next call. Otherwise, new instances are created only as necessary. :return: Returns a :class:`ZoneInfoFile` object. .. versionadded:: 2.6 N_cached_instance)getattrrrrr6)Z new_instanceZzifrrrr`s  cCs8tjdtttdkr(tjtttdjj |S)a+ This retrieves a time zone from the local zoneinfo tarball that is packaged with dateutil. :param name: An IANA-style time zone name, as found in the zoneinfo file. :return: Returns a :class:`dateutil.tz.tzfile` time zone object. .. warning:: It is generally inadvisable to use this function, and it is only provided for API compatibility with earlier versions. This is *not* equivalent to ``dateutil.tz.gettz()``, which selects an appropriate time zone based on the inputs, favoring system zoneinfo. This is ONLY for accessing the dateutil-specific zoneinfo (which may be out of date compared to the system zoneinfo). .. deprecated:: 2.6 If you need to use a specific zoneinfofile over the system zoneinfo, instantiate a :class:`dateutil.zoneinfo.ZoneInfoFile` object and call :func:`dateutil.zoneinfo.ZoneInfoFile.get(name)` instead. Use :func:`get_zonefile_instance` to retrieve an instance of the dateutil-provided zoneinfo. zzoneinfo.gettz() will be removed in future versions, to use the dateutil-provided zoneinfo files, instantiate a ZoneInfoFile object and use ZoneInfoFile.zones.get() instead.
